Overview of CARMAN SCAN VG

The increased vehicle emissions resulting from the drastic increase in the number

of vehicles has now reached levels that threaten life on the earth.

Accordingly, the vehicle-related laws and regulations of the advanced countries

aim not only to reduce the exhaust gas emissions and prevent the global warming

but also to abandon the development of gasoline engines and promote the

development of new technology (e.g. electric/hydrogen cars). For this purpose

various laws and regulations (e.g. OBD2/EOBD4) have been established or

strengthened to encourage automakers to invest in high-cost and long-term

development.

Due to the widening gap between advanced car maintenance technology and the

skills of maintenance staff, the distribution level of maintenance technology is

absolutely low, increasing the time it takes for maintenance staff to identify the

cause of failures and troubleshoot vehicle problems. i.e., from the perspective of

economics and technology, maintenance staff are facing new challenges in

acquiring and utilizing the wide range of equipment required to measure and

analyze the various parts and systems.

This CARMAN SCAN VG includes the necessary measuring functions and serves

as a guideline for car maintenance to help staff understand the ever-changing

technologies in a short period of time. It also has a recording function allowing

recording of abnormal signals, which can then be replayed for analysis.

CARMAN SCAN VG is a complete integrated vehicle information measuring system

which delivers the car maintenance information of domestic vehicles in real time,

and which has the intelligent self-diagnosis and recording function, satisfying the

requirements of the information age.

To utilize the various measurement and diagnostic functions of CARMAN SCAN VG

and enhance the efficiency of maintenance work to the maximum extent, it is

essential to read this user manual carefully.

POINT)

▶ The battery charging time of CARMANSCAN VG is about 8 hours,

however, it will vary depending on the usage situation.

▶ For the newly purchased battery or a battery which has not been

charged for 1 or more months, charge it fully first before use.

▶ If the surrounding temperature is too low or high, the battery charging

capacity is decreased.

▶ If you charge a battery immediately after using it, the battery may not be

charged due to the activation of the battery protection function resulting

from high battery temperature. In this case, wait for a while until the battery

temperature is lowered.

21


IV. Battery

2. Use of Battery

This section describes how to use the battery of the CARMANSCAN VG.

1) Disconnect AC adaptor and press the power button.

POINT)

▶ If the surrounding temperature is low, the battery operation time is

shortened.

▶ The operation time of a fully charged new CARMANSCAN VG battery is

about 1 – 2 hours, however, it varies depending on the usage situation.

▶ If the battery temperature increases, the operation of the product may

become slow. In this case, connect AC adaptor.

2. Check of Remaining Battery Power

If the product is powered on, you can check the remaining battery power

level displayed in percentage (%) under the battery icon on the right top of

a screen.

usage environment (e.g., the number of charges and discharges).

22


IV. Battery

3. Cautions in Handling

● The Battery is a very sensitive product. Do not give strong impact to it when

installing or removing it. For safety reasons, do not use a battery pack, which has

been severely shocked.

- A severely shocked battery may cause an electric shock or a rupture.

● Do not disassemble it.

- If you touch the inside of a battery after breaking it down, it may cause an

electric shock or a fire.

● Discharging

- A charged battery discharges power little by little even if you do not use it.

So, it is recommended to charge it right before using it.

- If you do not use a battery for a long time (e.g., I or months), remove and

store it in a cool place.

● About the lifetime

- If you do not use the mainframe for a long time, this may consume the

battery and weaken its power.

- Use the mainframe at least once a month and check the battery status.

- Leaving a battery in a high-temperature place may consume the battery and

weaken its power.

- Since a battery is a consumable product, using it for a long time may

decrease its charging capacity. In this case, replace it with a new one.

- If the battery operation time is excessively short, it means that the battery

lifetime has come to an end.

- Remove the used-up battery from the mainframe. Otherwise, it may cause

an electric shock or a fire.

● Disposition

- When disposing a battery, put an insulation tape over the battery connector

and take other necessary actions to prevent disconnection.

● Battery operation time

- The surrounding temperature affects the operation time of a battery. If the

temperature is low, the operation time may be shortened.

However, when the vehicle ignition switch is off or upon starting a vehicle,

power is not supplied to the cigar lighter socket.

2. Vehicle Battery

Connect the red clip of the battery connection cable to the (+) battery

terminal, and black clip to the (-) terminal. Connect the cigar lighter cable

between the battery connection cable and the product.

In this case, power is supplied anytime regardless of the ignition switch

status or vehicle starting.

Be careful when connecting the cable, as incorrect polarity may

damage the mainframe.

3. DLC Main Cable

Where the vehicle satisfies the OBD-II communication convention and uses a

16-pin diagnostic connector, the DLC main cable can supply power to the

product directly without a separate power supply.

4. Battery

The built-in battery can run the product for 1-2 hours without separate

power supply.

TIP)

The battery operation duration may vary depending on the usage and

environment.

4. AC/DC Adapter If AC/DC adapter is used as a power supply, the battery may be charged

automatically, and it may be used as the power source of the mainframe.
